Keep Honking buddy...
So i'm riding home today and i see a bus closing its doors in front of me about 20 yards away. He doesn't signal and starts going into the middle lane REALLY slow because its a red light (its a 3 lane st). As he's about half way pass the right lane i begin passing him at about 25mph and and hes starts honking away at me even after i've passed him. I counted maybe 10-15 honks. Mind you, this was in brooklyn, the buses in the city are much more courteous and always let me pass before they take off from their bus stop.
